The house thing his D was worried about? When she was way studying she was head tenant on the lease for the flat which she shared with a few girls she'd never met before.
Now that she's left and the quarterly bills are coming in, they're trying to get her to pay her share of the bills. She's still paying her share of the rent as she hasn't been able to find another tenant to take her place, but she doesn't want to pay the bills as she's not using any of the electricity or heating etc.
Because her name is on the lease as head tenant, I think there are some sort of legal implications, which she probably didn't realise. I think she's going to try and get her name taken off, but it sounds a bit stressful.
